"When it comes to South Korea, human rights guarantees for sexual minorities are insufficient," Yang Heezy, a drag queen and the organiser of Seoul Drag Parade, told AFP.

"Today's drag parade and more queer culture festivals should take place to bring attention to sexual minorities and help those who are not from those minorities learn more," he added, sporting a flame red wig and floral dress.

Both South Koreans and foreigners participated in Saturday's parade.

One participant, who gave her drag queen name Lola Bank, said there was a feeling of exhilaration among marchers.

"The fact that we are able to be in public in drag is a huge milestone to queer acceptance in Korea," Lola enthused, dragging on a cigarette.

"I’ve always struggled with my masculinity and my femininity. And when I get in drag I’m saying kind of like a 'fuck you' to society’s expectations of how I should behave as a male."

Gay pride parades have been a fixture in South Korea for years but have often been protested by religious groups, who have held rival anti-homosexuality rallies while trying to physically block marchers.

Even left-leaning South Korean President Moon Jae-in -– a former human rights lawyer –- said he "opposed homosexuality" during a campaign debate last year.

Gay rights activists claim that some progress has been made in recent years, with surveys showing increasing tolerance -- particularly among young people -- and growing participation at gay pride events.

Saturday's small parade saw no counter-demonstration.

Lee Hyang-soon, an elderly street vendor, smiled and waved to participants as they passed.

"It's really cool. Seeing all the foreigners join in, it feels like Korea is becoming world famous," she said. "I'm happy. It's fabulous."
